With many illustrations, John Hubert leads you on easily accessible field trips to Late Triassic-Early Jurassic rocks in the Connecticut Valley of western Massachusetts. John writes about the rocks in non-technical language, with geologic terms explained as introduced. The trips are a hands-on experience of the evidence allowing you to visualize now vanished mountains, rivers, playas, lakes, deltas, alluvial fans, and volcanic lavas, along with the dinosaurs that roamed the rift valley.
